Single fingerprint, misspellings pointed FBI to mail bombs suspect

A single fingerprint and several misspelled words were among some of the clues that pointed the FBI to a Florida man who was charged Friday with mailing homemade bombs to prominent Democrats, The Washington Post reported.

Cesar Sayoc Jr., a supporter of President Trump, was arrested Friday in connection with a series of 13 suspicious packages and pipe bombs that were sent to high-profile Democrats including former President Obama, former Secretary of State Hillary Clinton and former Vice President Joe Biden, among others.

FBI Director Christopher Wray said at a press conference following Sayoc's arrest that investigators were able to find a fingerprint on the envelope of a bomb sent to Rep. Maxine Waters (D-Calif.).

The fingerprint marked a breakthrough for investigators, who were able to gather Sayoc’s cellphone records and track his surveillance in Florida, an official told The Post.
